If I wait 2ms between each transfer they never get stuck.
As you mentioned in your other post, no usbdump yet in 8.0
But I can positively say that:
1. the transfer got submitted and the submit returned 0
2. no device NAK's on the USB bus (I'm looking at it with a sniffer)
So its definitely getting held in libusb/kernel
